+Subject: [PATCH] Page: Fix title delegate elision glitch
+
+Implicitly sized items like QtQuick/Text don't play nicely with Loader,
+and generally with kinda-recursive bindings on Layout.* properties.
+
+This combination of two fixes does the trick:
+
+1. Use extra TextMetrics for reliable width/height values.
+2. Round up text's advance width, so that container loader or layout
+won't ever round it down (which it did with implicitWidth before).
+
+(cherry picked from commit bc03a15b52c7512a1757da77963be5e1e48d5df1)

+Subject: [PATCH] Page: Split default page title delegate into separate
+ component
+
+There's no need to clutter Page component with potentially unused Items
+and IDs, and an extra self-contained component wouldn't hurt.
